Toughening of complete solid solution cermets by graphite addition
(Elsevier, 2015)
(Ti0.95Ta0.05)(C0.5N0.5)-Co complete solid solution cermets (CSCs) were developed by a mechanochemical synthesis process and a pressureless sintering method. The effect of different percentages of graphite used as a sintering ...

Design, processing and characterization of titanium with radial graded porosity for bone implants porosity for bone implants
(Elsevier, 2016-07)
Titanium cylinders with radial graded porosity, which are potentially suitable for biomedical applications (replacement of cortical and trabecular bones involved in different joint and dental restorations), have been ...

Sol-gel deposition of hydroxyapatite coatings on porous titanium for biomedical applications
(Elsevier, 2018)
The stress shielding and the poor osseointegration in titanium implants are still problems to be resolved. In this context, this work proposes a balanced solution. Titanium samples were fabricated, with a porosity of ...

Influence of the Test Configuration and Temperature on the Mechanical Behaviour of WC-Co
(MDPI, 2020-02)
In this work, the effect of the test configuration and temperature on the mechanical behaviour of cemented carbides (WC-Co) with different carbide grain sizes (dWC) and cobalt volume fractions (VCo), implying different ...

Use of Impedance Spectroscopy for the Characterization of In-Vitro Osteoblast Cell Response in Porous Titanium Bone Implants
(MDPI, 2020-08)
The use of titanium implants with adequate porosity (content, size and morphology) could solve the stress shielding limitations that occur in conventional titanium implants. Experiments to assess the cellular response ...

Characterization and Monitoring of Titanium Bone Implants with Impedance Spectroscopy
(MDPI, 2020-08)
Porous titanium is a metallic biomaterial with good properties for the clinical repair of cortical bone tissue, although the presence of pores can compromise its mechanical behavior and clinical use. It is therefore necessary ...

Effect of sintering time on the microstructure and mechanical properties of (Ti,Ta)(C,N)-based cermets
(Elsevier, 2013)
Complete solid-solution cermets based on titanium-tantalum carbonitride using a starting nominal composition with 80 wt.% of (Ti0.8Ta 0.2)(C0.5N0.5) and 20 wt.% of Co were performed by pressure-less sintering at 1550 C for ...

Effect of tantalum content on the microstructure and mechanical behavior of cermets based on (TixTa1-x)(C0.5N0.5) solid solutions
(Elsevier, 2014)
Titanium-tantalum carbonitride, (Ti, Ta)(C, N), based cermets with different Ti and Ta contents were prepared using a mechanically induced self-sustaining reaction and then densified using a pressureless sintering process. ...

Estudio de biocompatibilidad y osteointegración de nuevos materiales protésicos
(Ibáñez & Plaza, 2020)
Objetivos Los implantes óseos son utilizados cada vez con mayor frecuencia en la práctica clínica y, entre los materiales, el Ti o sus aleaciones son los de mejor rendimiento por sus propiedades fisicoquímicas. Aleaciones ...

Influence of temperature on the biaxial strength of cemented carbides with different microstructures
(Elsevier, 2018)
The effect of the temperature on the mechanical strength of WC-Co cemented carbides with different microstructures (grain size and binder content) was evaluated. Biaxial flexural tests were performed on three cemented ...
